The Sumitomo Spirit/ Sumitomo Riko Group Management Philosophy

Sumitomo's business has been conducted based on the "Monjuin Shiigaki," the business principles written by Masatomo Sumitomo, the founder of the Sumitomo family about 400 years ago, and the spiritual basis of the "Sumitomo Spirit," which has been deepened and developed by Sumitomo's predecessors over many generations.

Monjuin Shiigaki

It goes without saying that business is important, and one must be mindful, careful and prudent in everything one does. One shouldn’t be careless in anything one does. (Banji-nissei)

Business Principles
Article 1.
Sumitomo shall achieve prosperity based on a solid foundation by placing prime importance on integrity and sound management in the conduct of its business. (Shinyo-kakujitsu)
Article 2.
Sumitomo's business interests must always be in harmony with the public interest. Sumitomo shall adapt to good times and bad times but will not pursue immoral business. (Fusu-furi)

The Sumitomo Spirit


First of all, as a human being, one should be a person who does everything with sincerity and integrity in everything they do.


Above all, we value trust.
In other words, to always live up to the trust of others.


Always seek alignment with the public interest,
And pursue the highest interest.
Do not act rashly or carelessly.

The Sumitomo Spirit is the fundamental spirit of our Group's business management and the basis for all our employees' decisions in all business operations.
Our Group places the Sumitomo Spirit at the center of our human resources development. We provide training for all our employees using the video "Our Sumitomo Spirit" to encourage a deep understanding of the philosophy, and we try to put it into practical operations.
